I payed extra for this bluetooth, and the echo is unbareable to the person on the other side. I turned the volume all the way down on the unit, and on my phone. And either they can still hear themselves talking, or I can't hear a word they are saying.
I have a Bose Surround Sound system in my silverado, don't know if that has anything to do with it. I have tried relocating the mic from the top of the windshield to in the cieling in the OnStar mic location. A little better, but still annoying.
Anyone?
